| ( 4 ) 2) PEREGRINE STEERING N.SCH. 4.216 STIFFR TORSION SHAFT. With the new standard front Axle, the steering has been selective and stable. It was not free from steering re-actions on rough roads. We fitted an extra stay to the column, to try and prevent the whipping of the column. The top portion of the column still whips considerably when travelling over uneven surfaces. We have run the latter part of the mileage with the thick leaf front road springs anchored at the rear. Damper initial poundage 90 lbs. The condition of the steering box is good. No slackness has developed, and it has been free from oil leaks. 3) STANDARD BRAKING SYSTEM WITH IMPROVED SERVO OF THE CRINKLY PLATE TYPE HAVING MODIFIED LINING FIXING. Upon dismantling the servo at 10.000 miles, we found that the wear of the fabrics had allowed a boss inside to foul. This had to be cut away, to allow the contact of the linings. A report and sketch was sent, dealing with this fault. The Servo has been effecient. The fault previously reported of loss of effeciency, still prevailed with excessive use of the Brakes. 4) I4 " BRAKE DRUMS WITH WATER EXCLUDERS. The water Excluders were satisfactory during the period they were in use. 7) RUBBER ENGINE MOUNTING LEC 3895 N. SCH. 4167 The rubber mounting of the Engine at the front became very slack, owing to the wear of the bottom rubbers and no stay being fitted, to take the effect of the drive. The Engine moved crosswise, as well as backwards. We reduced the distance tubes in the front rubber block by 1/16 which tightened up the bottom block. This steadied the Engine. We have just received a stay, that should have been fitted in the first place to the front cross member and the O.S. Engine bearer. This would overcome the backward movement, but would not cure crosswise motion. The extra stay we fitted to the Clutch.Pedal, helped to steady the Engine. We had fitted new rubber blocks the day the Engine failed. | ||
